Free online 40 minute timer
A 40 minute timer that tracks real focus
40 minutes sits between Pomodoro and a true deep work block. TimerDuel adds a chess-clock so you see exactly how much of those 40 minutes was focused work — not just elapsed time at your desk.
When 40 minutes is the right length
- • Exam practice. Many test sections run ~40 minutes. Train under realistic time pressure.
- • Study block. Long enough for depth, short enough to do twice in a sitting.
- • Long workout. A full session with a clear finish line.
- • Class-length sprint. Simulate a school period.
